In fact, tool passivation is not a literal understanding of the word, but a way to improve tool life. Improve tool quality through processes such as leveling, polishing, and deburring. This is actually a normal process before the coating is finished after the grinding. Many friends have such a question. The CNC tool used in the machining center is not as fast as possible. Why should it be passivated? In fact, tool passivation is not a literal understanding, but a way to improve tool life. Improve tool quality through processes such as leveling, polishing, and deburring. This is actually a normal process before the coating is finished after the grinding. The tool will be sharpened by a grinding wheel before the finished product, but the sharpening will result in different levels of micro-notch. The machining center can perform high-speed cutting while the micro-notch can be easily expanded to accelerate tool wear and damage. In modern cutting technology, the stability and precision of the tool are strictly required. Therefore, the CNC tool must pass the passivation treatment before the coating to ensure the firmness and service life of the coating. What are the benefits of tool passivation? 1. Resistance to physical wear of the tool During the cutting process, the surface of the tool will be gradually worn out by the workpiece. During the cutting process, the cutting edge is prone to plastic deformation under high temperature and high pressure. The passivation of the tool helps the tool to increase rigidity and avoid premature loss of cutting performance. 2. Maintain the smoothness of the workpiece A burr on the edge of the tool can cause the tool to wear and the surface of the machined workpiece can become rough. After passivation, the cutting edge of the tool will become smooth, the chipping phenomenon will be reduced, and the surface finish of the workpiece will be improved. 3. Convenient groove chip removal Polishing the tool groove improves surface quality and chip removal performance. The flatter and smoother the groove surface, the better the chip removal, for a more consistent cutting process. After the passivation and polishing of the CNC tool in the machining center, many small holes will be left on the surface. These holes can absorb more cutting fluid during processing, which greatly reduces the heat generated during cutting, which greatly improves the cutting process. speed.
Our Trumony designs, makes and distributes heat exchangers for battery packs. For the prismatic cells what we provide the solution is aluminum brazing water cooling plates. The water liquid cold plates are generally made by 2 aluminum sheets what are upper plate and down plate. The upper plates are shaped with flow channel through stamping process, and then combined with down plate by laser spot welding and brazing processes. In addition,the cooling plate is with inlet& outlet. When the water/glycol as the coolant liquid flow in the channel , the heat will be transferred to realize battery cooling.
